Abstract

By utilising ionic liquids the pharmaceutically active triterpene betulin can be extracted from biomass with significantly improved extraction yield and purity. The recovery of the ionic liquid 1-ethyl-3-methylimidazolium acetate via azeotropic distillation of EtOH/H2O was successfully demonstrated.
